This study discusses the soliton and other solutions for a weakly nonlocal Schr¨odinger equation of
the fifth order involving nonlinearity of the parabolic law and an external potential. We use
solitary wave ansatz of different forms to obtain bright, dark, singular, periodic soliton and
exponential solutions. The results obtained can be useful in understanding and interpreting the
wave dynamics of the proposed model.
